Warsaw - Polish resistance fighter Irena Sendlerowa, who organized the rescue of 2,500 Jewish children from the Warsaw Ghetto during Nazi occupation, died Monday aged 98, Polish radio reported.

Sendlerowa was part of the Zegota resistance movement. Together with a group of 20 helpers, she smuggled 2,500 children out of the Warsaw Ghetto in ambulances, through sewers and once under her skirt.

She then obtained forged identity cards for them and hid the children with foster families, at monasteries and orphanages.
